as most folks who hang around here know, i received my nMP and have been putting it through the paces as i figure out if it will meet my needs (still photography; audio; at least one VM at all times; only casual video use). i've been evaluating it vs a 2013 iMac. as part of my move from my older Mac Pro to either solution, i decided to commit to a mostly external storage system via thunderbolt. i evaluated a number of enclosures (sonnet echo express iii-d, pegasus2 r4, OWC mercury elite pro dual, promise j4, and more), and i settled on the sonnet as the winner for my setup. it provided faster results in my testing than any other enclosure, and it more than doubled the performance of some (*cough* OWC *cough*). tonight i did a test where i compared the very same drive setup (2x840EVO1TB on a Tempo Pro in the Sonnet) connected to the iMac, and then a few minutes later connected to the nMP. I figured I'd get the same results -- nothing to report, right? Wrong. I'll let the images speak for themselves, but on QB4.0 I was seeing the following for reads/writes for nMP vs iMac: 4k-1024K randoms: 317/339 vs 289/289 4k-1024k sequentials: 391/343 vs 363/305 2-10MB: 801/737 vs 785/645 20-100MB: 828/767 vs 830/678 via Blackmagic (5GB), I was seeing 814/737 on the nMP and 790/640. the nMP is TB2, but i have not yet upgraded the card in the sonnet enclosure to the new TB2 version! (i will do that next week. i imagine the results may be a bit better. as a point of reference, the iMac PCIe SSD's (Samsung 512) random reads/writes are 207/372 vs the nMP PCIe SSD's (Samsung 512) 255/419. for larger transfers the iMac hits 781/722 while the nMP hits 1222/1061. those tests were all run when each machine was new. you can see more detail in the attached screenshots (results for 4k-1024k & 2-10MB in this message; the rest in the next one). hope this is helpful to some folks.
